Vacuum Cleaner
A wasserfilter staubsauger is an appliance utensil with a air pump creating a vacuum which causes the suction of dust and small waste fell to the ground. This type of tool used for cleaning carpets and rugs. The dust is collected either in a bag that serves as primary filter or in a removable hard collector using a centrifugal system (see Dyson). The first cleaning system using vacuum cleaner to suck the dust was manual. This is the Whirlwind, invented in Chicago in 1869 by Ives W. McGaffey [1]. This lightweight and compact machine was difficult to use because it had to turn a crank while pushing on the ground. Patented June 8, 1869, this unit was sold for $ 25, a very high price for the time. We do not know what was the success of the Whirlwind, but most devices were sold in Chicago and Boston, it is likely that most were lost in the great fire which devastated Chicago in 1871. Only two copies have survived, one of which is at the Hoover Historical Center (Ohio). The vacuum cleaner motor was invented in 1901 by Hubert Cecil Booth, a British engineer. He had noticed that the cleaning of train seats by dusting would be advantageously replaced by a system that sucks the dust rather than to fly elsewhere. After trying to suck himself the dust of a seat through a handkerchief, he has applied the process in a device known as the Puffing Billy. This cumbersome system was to be towed by horses in front of the building to clean, the suction being caused by a gasoline engine. Too restrictive, the invention of Booth has not been successful. In 1905, Griffith's Improved vacuum cleaner Apparatus for Removing Dust from Carpets ("Apparatus improved Griffith vacuum cleaner to remove dust mats") is patented by Walter Griffiths. This is a new manual system easily transportable, easy to store and can be used by one person. The operator must press a system of bellows that sucks dust through a hose and removable end caps which several can be attached. This is the first vacuum cleaner vacuum comparable to current. In 1906, James Murray Spangler, concierge Canton, Ohio, invented an electric vacuum cleaner from a fan, a box and a pillowcase. Spangler model also incorporates a rotating brush to loosen dirt more easily. Patented in 1908, the system is sold to the company of his cousin William Hoover: Hoover Harness and Leather Goods Factory, which appoints mechanical suction brush [2]. Hoover remains one of the world's leading vacuum cleaner, so the word has passed into everyday language (in England, called the vacuum cleaner hoover while "vacuum" is commonly said to hoover) . In some environments such as cinemas, conference facilities and trains, agents use back-end vacuum cleaners. Battery or mains, they allow faster travel. There is also the upright vacuum cleaner scrubber (upright), equipped as its name indicates an electric brush. This allows thorough cleaning of the carpet. However, in the long run, it causes wear of the coating. Past ten years, bagless vacuum cleaners were introduced and gradually eat away market share from traditional models.
